Inventor: JONTE PATRICK
IPC: B05B12/08
Filed: 2005-04-07
Abstract: A fluid control system includes a valve and a restrictor. The valve is configured to regulate the proportion at which a first fluid and a second fluid are mixed together. Based on the pressure drop across the restrictor, the valve further regulates the overall flow rate of the mixed first and second fluids. In one form, the valve includes a pair of spools that regulate the proportion and flow rate of the fluids. In another form, the valve includes a thermostatic element that regulate the proportion at which the first and second fluids are mixed together so as to control the temperature of the mixed fluids. The valve in a further form incorporates a pair of diaphragm valves.

IPC: C08J7/056
Filed: 2003-12-19
Abstract: The present invention relates to hydrophilic polymeric compositions for maki ng a liquid impermeable moisture vapour permeable structure, for example by forming the composition into a layer or coating onto a suitable substrate fo r example a microporous film and to composite structures comprising the compositions. The hydrophilic polymeric compositions of the present inventio n do not solidify at room temperature, but remain viscous or "creamy". This prevents layers made from the hydrophilic polymeric composition of the prese nt invention from settling as a film so that delamination of a composite structure comprising the hydrophilic polymeric composition coated into a lay er onto a suitable substrate is avoided. The hydrophilic polymeric compositions of he present invention can find a variety of applications wherein liquid imperviousness and moisture vapour permeability are desirable.

Inventor: MILLER FERGUS RONALD
IPC: E04C5/06
Filed: 2004-05-06
Abstract: A flooring of pre-stressed deck construction has an elongate decking (10) extending along the flooring, the decking (10) having an upwardly facing asymmetrically profiled channel formation (11) whereby the neutral axis is above a central horizontal plane. A tension rod (40) extends between stressing brackets (20) secured to each end of the decking (10) and is located below the neutral axis of the decking (10) along the length of the decking (10). Each stressing bracket (20) is secured to upwardly extending sidewalls (13) of the channel (11) above the tension rod (40). The decking (10) is attached to the girder framework (44) of a building. Since the tension rod (40) is below the neutral axis of the decking (10), the bending stress applied to the decking (10) is positive, causing upward arching of the decking (10). This is stress relieved when the concrete flooring (53) is applied to the decking (10). Since the attachment of the stressing brackets (20) to the decking (10) is above the tension rod (40), there is no negative bending stress applied to the ends of the decking (10). In fact, the positive bending stress applied is enhanced by this configuration.

Title: Low loss poppet valve for a cleaning device
Inventor: HABIB TONY F
IPC: F28G1/16
Filed: 2006-06-28
Abstract: A poppet valve for use with a sootblower for removing debris from an interior volume of a boiler is provided. The poppet valve assembly includes a valve housing and a valve head configured to move within the valve housing between an open position and a closed position. The poppet valve assembly enables the cleaning fluid to undergo relatively small pressure loss as it flows through the poppet valve assembly when the valve head is in the open position. More specifically, the poppet valve assembly has a loss factor that is substantially less than currently-known valve. The poppet valve causes the cleaning fluid to undergo relatively small pressure loss while flowing therethrough.

Patent CA-2554833-A1 (CA)
Inventor: WOODS JOHN T
IPC: F03G7/10
Filed: 2006-08-03
Abstract: In previous attempts to construct a perpetual motion machine, each device has found its own equilibrium without producing the anticipated results. In this series of designs (which represents a companion application to Canadian Application # 2545253), a very large sprocket (God Wheel) is engaged at diametrically opposite sides by (angel) sprockets via their common engagement of a multi-strand chain: One strand surrounds the large sprocket, while the second strand is available for engagement by the angel sprocket/s. The shafts of the engaging sprockets are held to a constant distance from the central god shaft, and in balance, by teeter arms, which pivot about the god shaft. On each of these same (angel) shafts is also a (cupid) sprocket, which engages an inboard harness chain on its proximal** side [found in the previous application] or an outboard harness chain on its distal side [found in this application]. Harness shafts above and below the god shaft, connect to it via a separate (brave) sprocket and a long bridle chain to a (crib) sprocket on the god shaft. Also found on the angel shaft are (forge) sprockets, each of which engages one strand of a multi-strand chain. Leverage is imposed via the forge wheel, against the angel wheel owing to the presence of a second set of (tug) sprockets. The tug sprockets exist on their own shafts, which also pivot about the god shaft via their own dedicated tug teeter arms.  The tug teeters are joined by a cross member at each end, against which force is imposed 'up' or 'down' i.e. at right angles, approximately, to the equatorial described by the placement of the teeter arms. The force imposed against the tug teeters forces the tug sprockets to attempt to travel/pivot about the god shaft; forcing the forge sprockets to turn with them; forcing the angel sprockets to turn with them; forcing the god wheel turn with them;  forcing the crib sprocket on the god shaft to turn; forcing the harness wheels to turn; forcing the cupid wheels to turn, but stay in place; forcing all elements to seek equilibrium perpetually, although they are perpetually unable to do so until force is removed from the tug cross members, or until the direction of force is reversed. In some variations, the forge sprocket also serves as the cupid element, negating the need for discrete cupid wheels.   All wheels turn synchronously, owing the compatibility of their ratios.  Any of many forms of force may be used to induce the motor reaction.  ** distal or proximal vis a vis the god shaft
